Stacking can be a controversial topic in many daily fantasy sports, but you can count baseball as a glaring exception. Here, it's universal.

Using multiple players on the same team on a given day presents you with the opportunity to double dip. If one of your players hits an RBI double, there's a good chance he drove in another one of your guys. When you get the points for both the run and the RBI, you'll be climbing the leaderboards fast.

Each day here on numberFire, we'll go through four offenses ripe for the stacking. They could have a great matchup, be in a great park, or just have a lot of quality sticks in the lineup, but these are the offenses primed for big days that you may want a piece of.

Premium members can use our new stacking feature to customize their stacks within their optimal lineups for the day, choosing the team you want to stack and how many players you want to include. You can also check out our hitting heat map, which provides an illustration of which offenses have the best combination of matchup and potency.

Now, let's get to the stacks.

Baltimore Orioles

The Baltimore Orioles have disappointed in some potentially lucrative spots this season, but it might be tough to pass them up against Dylan Covey, one of the worst pitchers on the slate. Over 76 career innings, Covey owns a 5.63 SIERA that only a mom could love, along with a 13.1% strikeout rate and 11.0% walk rate. Oh, and he's also allowed a .402 wOBA and 37.4% hard-hit rate to opposing hitters.

Since we aren't exactly dealing with a powerhouse offense, the Orioles are an inexpensive squad with the one exception (of course) being Manny Machado ($5,000). But he's that one guy you've got to have, bringing a .437 wOBA and .314 isolated power (ISO) to the shallow shortstop position.

Otherwise, we have Trey Mancini ($3,100), Adam Jones ($3,300), and Jonathan Schoop ($3,100) to round out the top of the order, and all are viable at these salaries. A traditional one-through-four stack should be quite manageable if that's the way you want to go.

Chris Davis ($2,300) and Pedro Alvarez ($2,600) are boom-or-bust options, but they're your cheapest ways to get exposure to this lineup, and both will benefit from the platoon advantage. Davis has come up empty more often than not this year, but he's posted a 50.0% hard-hit rate in May, so there's still hope he can start churning out those dingers. Meanwhile, Alvarez is displaying the power he's shown for much of his career with an impressive .292 ISO in 2018.

Mark Trumbo ($2,900) was dropped to seventh in the order on Tuesday, but he's putting up an encouraging 44.1% hard-hit rate and 93.5 mile-per-hour average exit velocity, so you can keep him in mind, as well.
